APJ ABDUL KALAM TECHNOLOGICAL UNIVERSITY
SIXTH SEMESTER B.TECH DEGREE EXAMINATION(R&S), MAY 2019

Course Code: CE 302
Course Name: DESIGN OF HYDRAULIC STRUCTURES

PARTA
Answer any two full questions, each carries 15 marks.
Explain the failure of hydraulic structures by sub surface flow.
Compare Kennedy’s theory and Lacey’s silt theory.
Explain the different types of weir with neat sketches.
What are the functions of an under sluice and silt excluder in a diversion
headwork?
Explain the different classifications of canal.
Write down the procedure for the design of a vertical drop weir.
Draw the section of unlined canal partly in cutting and partly in filling and
explain the parts
Two sheet piles of unequal length are provided at the two ends of an impervious
floor of 15m length and 1൩ thick. Total head created on the floor is 3m. Using
Khosla’s method of independent variables, calculate the uplift pressure at the key
points, if the upstream pile is 3m deep and downstream pile is 5m deep.
PART छ
Answer any one full question, each carries 50 marks.
Design a suitable cross drainage work for the following hydraulic particulars:
Discharge of the canal = 28 cumecs
Bed width of the canal = 20m
Depth of water in the canal = 1.6m
Bed level of canal = 250.00m
High flood discharge of the drainage = 400 cumecs
High flood level of drainage = 253.00m
Bed level of drainage = 248.00m
